Mental Math Units: the Complete Addition Collection

Front end addition is an extremely powerful mental math strategy for adding numbers with two or more digits. In this mental math strategy unit, students will learn to add two two-digit numbers using front end addition. This means adding the tens first, and then the ones. For example, for the equation 24 + 53, students will learn to first add 20 and 50 to make 70, and then 4 and 3 to make 7. Subsequently, the 70 and 7 can be added to equal 77. With repeated practice, students can become very quick and efficient adders when using this strategy. Once learned and practiced, this strategy is much more efficient and accurate than traditional vertical addition.

This is a very large mental math strategy pack that is separated into two sections to provide you with everything you need to teach and have your students practice front end addition. Included is independent seat work, flashcards, center activities, whole class kinesthetic learning activities and more! Section 1 focuses on front end addition without regrouping. This includes equations such as 23 + 34 or 65 + 12 where the ones digits never add to more than 9. In Section 2, students will learn and practice front end addition where regrouping is necessary. This includes equations such as 46 + 29 or 64 + 17 where the ones digits add to ten or more.

Enjoy!

So many great pages and made it very easy for students to understand! I was not a believer in this strategy when I was first introduced to this but my students have grasped on completely. I just wish the parents would too. A letter explaining how to add this way and why would help.

Front-end addition is such an important concept. This product came along at the perfect time when I realized my fifth graders did not understand. Now they are much better at mental math.

### Product Questions & Answers

Hi Shelley,
Does this unit cover sums that go over 100? My students have a good grasp of this strategy. But, when the sum carries over to 100, they get confused.

Thanks
Hi Timothy,

Most of the sums are less than 100 in this unit. Another item that you might be interested in is this Left-to-Right Addition Gallery Walk Combo Pack:

(Just copy and paste the link above into your browser.)

Let me know if you have any other questions,

Shelley
Hi Shelley,
I have had a wonderful time using the activities in the Front End Addition package. The problem solving cards are great. May I offer a suggestion? One improvement would to have 10 more problem solving cards with questions/solutions that do not involve regrouping (there is currently only one). Then my lower group could be working at the same time on similar activity as my advanced group.
Great idea! I am going to work on that this week and add it to the unit. If you send me your email address to shelley_gray_@hotmail.com I will send them to you when they are finished.

Thanks so much!

Shelley
